- 15 thick-skinned lemons (Eureka, Lisbon or Citron if you're in the US)
- 2 bottles (750 ml each) of the best 100 proof Vodka or a 750 ml bottle of 190-proof alcohol
- 4 1/2 cups (1 k) sugar
- 5 cups (1.2 liters) water if you use vodka, or 8 (2 liters) if you use grain alcohol
Add 1 bottle of Vodka, or half the alcohol, and stir. Cover the jar, date it, and put it to rest in a dark cabinet at room temperature.
After 40 days, take out the lemon-Vodka mixture. In a sauce pan set over high heat, stir the sugar and water together and boil for 5 minutes. Let the sugar syrup cool completely in the pan, about 10 minutes. Add the sugar syrup to the lemon-Vodka mixture along with the second bottle of Vodka or the remaining alcohol.
Stir well to combine. Replace the cover on the jar and note the finish date. Return it to the dark cabinet and store for 40 more days.
At day 80, remove the limoncello from the cabinet. Strain the mixture and discard the lemon peel.
Pour into clean, unused bottles with caps or decorative corked bottles. Store the bottles in the pantry, but put one bottle at a time in the freezer until ready to use.
Makes approximately 3 quarts.
Note: Grain alcohol is also known as Everclear, after a company that labels it as such.
